Abstract
Following a one-side transverse incision made into the middle stem part ofBryophyllum crenatum below one of the two opposite leaves, the leaf is exposed to an enhanced effect of correlatively inhibitory substances passing out of the apical part of the stem. Within 28 days this results in a formation of adventitious roots above the incision. The flow of correlatively inhibiting substances interrupted by the incision induces, as early as within 24 h, a decrease in the level of endogenous gibberellins in the leaf above the inoision.
